98 g of sodium thiocyanate were added to 300 ml of toluene, 100 ml of water and 5 g of a phase transfer catalyst. Thereafter, 181 g of thiophene-2-carbonyl chloride were added dropwise in the course of 1 hour and the mixture was stirred for 5 hours at from 20° to 25° C. The pH of the suspension was kept at 6-7. 168 g of bis(2-methoxyethyl)-amine were then added dropwise at from 20° to 25° C. in the course of 1 hour, after which the pH was corrected to 7-7.5 and stirring was continued overnight. 350 ml of water and 200 g of sodium hydroxide solution (50% by weight) were then added, and 124 g of chloroacetic acid were introduced at not more than 40° C. The mixture was then stirred for 5 hours with evaporative cooling. After the end of CO2 elimination, the aqueous phase was separated off and the organic phase was extracted twice by shaking with water. The organic phase was subjected to distillation under reduced pressure (bath temperature: not more than 155° C.). 250 g of the coupling component of the formula ##STR7## were obtained as a brown oil.
The procedure described in Example 1 was followed; except that, instead of thiophene-2-carbonyl chloride, 170 g of benzoyl chloride were used. 240 g of the coupling component of the formula ##STR8## were obtained as a viscous, greenish oil, which rapidly solidified to give a colorless, crystalline product of melting point 47° C.
13.8 g of 3-(2-methoxyethyl)-4-cyano-5-aminoisothiazole were dissolved in 160 ml of glacial acetic acid and 35 ml of propionic acid. The solution was then cooled to 0°-5° C., and 32 g of 42% strength by weight nitrosylsulfuric acid were added dropwise at this temperature, and stirring was carried out for 3 hours. The mixture was then poured into a solution of 29.7 g of the thiazole of the formula ##STR9## and 200 g of glacial acetic acid, 40 g of propionic acid and 30 ml of aqueous 10% strength by weight amidosulfonic acid solution. The mixture was then cooled to 0°-5° C. The coupling reaction took place immediately. The mixture was kept stirrable by adding about 800 ml of ice water and 200 g of ice. After the mixture had been buffered at pH 0-0.5 with sodium acetate, the precipitated dye of the formula ##STR10## was filtered off under suction, washed with water and dried to give 47 g of a dark red to violet powder which dissolves in N,N-dimethylformamide to give a reddish blue solution and dyes polyethylene terephthalate fabric in reddish blue to navy hues.
λmax 580 nm (9 : 1 v/v N,N-dimethylformamide/ glacial acetic acid).
13.8 g of 3-(2-methoxy-ethyl)-4-cyano-5-aminoisothiazole were diazotized similarly to Example 3 and the product was coupled with 27.9 g of the thiazole of the formula ##STR11## to give 48 g of a dark red powder of the formula ##STR12## which dissolves in acetone to give a violet solution and dyes polyethylene terephthalate fabric in violet hues with excellent lightfastness. The dye has very good build-up properties.
λmax : 554 nm (9 : 1 v/v N,N-dimethylformamide/ glacial acetic acid).
17.2 g of 3-methyl-4-thiocyanato-5-aminoisothiazole were dissolved in 220 g of glacial acetic acid and 48 g of propionic acid at about 45° C. The solution was then cooled to 0°-5° C., 32 g of 42% strength by weight nitrosylsulfuric acid were added at this temperature and stirring was carried out for 3.5 hours at from 0° to 5° C. The resulting solution was added to a mixture of 29.2 g of 2-bis-(2-methoxyethyl)-amino-4-phenylthiazole, 50 g of glacial acetic acid and 10 g of an aqueous 10% strength by weight amidosulfonic acid solution. 8 g of concentrated hydrochloric acid and 400 g of ice water were also added and the mixture was cooled to 0° C. with ice. The coupling mixture was buffered at pH 0.8-1 with dilute sodium acetate solution. The precipitated dye of the formula ##STR13## was filtered off under suction, washed and dried to give 42 g of a reddish violet powder which dissolves in N,N-dimethylformamide to give a violet solution and dyes polyethylene terephthalate in strong dull bluish red to violet hues.
λmax : 542 nm (9 : 1 v/v N,N-dimethylformamide/ glacial acetic acid).
20.7 g of 3-(thien-3-yl)-4-cyano-5-aminoisothiazole were sprinkled into a mixture of 125 g of sulfuric acid (71% strength by weight), 22 g of glacial acetic acid and 32 g of nitrosylsulfuric acid (42% strength by weight), cooled to 0° C. The diazotization mixture was stirred for 4 hours at from 0° to 5° C., and a yellow suspension was obtained. This mixture was combined at <8° C. with a solution, cooled to 0°-5° C., of 42.4 g of the thiazole of the formula ##STR14## in 300 g of glacial acetic acid, 50 g of propionic acid, 50 g of ice and 1 g of amidosulfonic acid. During introduction of the diazonium salt, a little ice and ice water were added simultaneously so that the mixture remained stirrable. Stirring was continued for 10 minutes at about 0° C., after which the mixture was buffered at pH 0.2-0.4 with dilute, ice-cold sodium hydroxide solution. The dye of the formula ##STR15## was isolated similarly to Example 5. It dissolves in N,N-dimethylformamide to give a solution having a navy hue and dyes polyethylene terephthalate in strong, blue hues. λmax : 588 nm (9 : 1 v/v N,N-dimethylformamide/ glacial acetic acid).
The dyes listed in Tables 1 to 4 below are obtained in a similar manner.

13.9 g of 3-methyl-4-cyano-5-aminoisothiazole were dissolved in a mixture of 210 ml of glacial acetic acid and 50 ml of propionic acid at 50° C. The solution was then cooled to 10° C., after which 14 g of concentrated sulfuric acid and then, at from 0° to 4° C., 32 g of nitrosylsulfuric acid (45% strength by weight) were added dropwise. The mixture was stirred for 3 hours at from 0° to 5° C., after which a clear diazonium salt solution was obtained. This was run, with thorough stirring, into 30 g of the coupling component of the formula ##STR73## dissolved in a mixture, cooled to 0°-5° C., of 150 g of glacial acetic acid, 40 g of propionic acid and 0.5 g of urea. During this procedure, the temperature was kept at ≦5° C. by cooling. Thereafter, the mixture was buffered by adding sodium acetate at ≦5° C. in such a way that the free sulfuric acid was bound (pH of the mixture about 0.5-1.5). The resulting dye of the formula ##STR74## was precipitated by adding water, filtered off under suction, washed and dried. Yield: 43 g.
The dye dissolves in N,N-dimethylformamide to give a bluish red solution and dyes polyester fabric in lightfast, bluish red hues. The absorption maximum, measured in a mixture of N,N-dimethylformamide and glacial acetic acid (9 : 1 v/v), is 526 nm.
13.9 g of 3-methyl-4-cyano-5-aminoisothiazole were diazotized similarly to Example 80 and the product was combined with 29 g of the coupling component of the formula ##STR75## which had been dissolved in a mixture of 150 g of glacial acetic acid and 40 g of propionic acid at 2° C. Thereafter, 35 g of dry sodium acetate were sprinkled in while stirring and cooling at ≦6° C., the coupling reaction being initiated.
After the end of the reaction, the resulting dye of the formula ##STR76## was precipitated with water and was isolated similarly to Example 1. 42 g of a dark red powder were obtained, the said powder dissolving in N,N-dimethylformamide to give a pale bluish red solution and dyeing polyester fabric in bluish red hues having very good fastness properties. The UV spectrum has a virtually symmetric curve in the visible spectral range. The absorption maximum is 525 nm.
13.9 g of 3-methyl-4-cyano-5-aminoisothiazole were dissolved at 50° C. in a mixture of 210 ml of glacial acetic acid and 50 ml of propionic acid. The solution was then cooled to 10° C., and 14 g of concentrated sulfuric acid (96% strength by weight) were added dropwise. Thereafter, the suspension was cooled to 2°-4° C. and 32 g of nitrosylsulfuric acid (44% strength by weight) were added dropwise at this temperature. After stirring had been carried out for 3 hours, a clear diazonium salt solution was obtained. Excess nitrous acid was then destroyed with urea. The diazonium salt solution was then run into a solution of 25.0 g of the coupling component of the formula ##STR77## in 160 ml of glacial acetic acid and 40 ml of propionic acid. The solution was cooled to 2°-4° C. After the addition of the diazonium salt, the dye of the formula ##STR78## was obtained. The dye was precipitated by adding water. After the mixture had been buffered at pH 0-0.5 with sodium hydroxide solution, the dye was isolated by filtration under suction, washing with water and drying. 39.6 g of a bluish black powder were obtained, the said powder dissolving in N,N-dimethylformamide to give a reddish blue solution. The absorption maximum, measured in a mixture of N,N-dimethylformamide and glacial acetic acid (9 : 1 v/v), is 577 nm.
The dye dyes polyester fabric in reddish blue to navy hues.
Because of its good affinity to polyester fibers, it is also suitable for (sublimation) transfer printing.
The dyes listed in Tables 6, 7 and 8 below are obtained in a similar manner.
